Abstract

The office chair locking mechanism comprises a transverse arm (32) fixed to a support frame below the seat. Slotted housings (72,74) are fixed to the underside of the seat and close to the outer ends of the arm, with the slots in them open to the inside. A sliding and locking member (66), turning on each arm end, fits in the oblong slot in the respective housing and allows sliding of the seat when turned into a first position. It locks in the slot, when turned into a second position, in which its effective dia. between the slot walls is greater than in the first position. It can typically be of hexagonal cross-section.
